maskedit in cell of gridControl

[Fady Sayegh]

hi to all,

i''m using the gridControl in my win form application.

i have a cell that contains a maskedit, i set the
property Mask like this :
oGrdC.ColStyles[i + 1].MaskEdit.Mask = "__/__/___";

when i run the program, i can''t enter data. i works only when i set the property to " / / "

how can i put the first mask ("__/__/____") for the date

best regards and thanks in advance

Hi Fady,

Could you try this code

oGrdC.ColStyles[i + 1].CellType = "MaskEdit";
oGrdC.ColStyles[i + 1].MaskEdit.Mask = "99/99/9999";

Let me know if you need any further assistance.

Hi Haneef,

thanks to your reply,

in fact that''s what did i do, but this 2 lines of code

oGrdC.ColStyles[i + 1].CellType = "MaskEdit";
oGrdC.ColStyles[i + 1].MaskEdit.Mask = "99/99/9999";

gives this mask at run time " / / " or i need to have this one "__/__/____", in other words i need to display the underscores in the mask. but when i do that the gridControl does not accept any input from the user in the maskedit cell

best regards and thanks in advance

Hi Fady,

You need to set the PaddingCharacter and PromptCharacter property of the MaskEdit Celltype in a grid.Here is a code snippet.

oGrdC.ColStyles[i + 1].CellType = "MaskEdit";
oGrdC.ColStyles[i + 1].MaskEdit.Mask = "99/99/9999";
oGrdC.ColStyles[i + 1].MaskEdit.PromptCharacter = ''_'';
oGrdC.ColStyles[i + 1].MaskEdit.PaddingCharacter = ''_'';

Here is a sample.

Hi Haneef,

thanks to your reply, it works

but how can i verify if the date (54/26/2006)entered by the user is valid. is there a way to validate the date when the user leave the cell

for example, if the date is not valid and when the user leave the cell : clear the cell

best regards and thanks in advance

Hi Fady,

To validate the current cell in a grid, you need to handle grid''s CurrentCellValidateString event.Here is a code snippet

GridCurrentCell cc = this.gridControl1.CurrentCell;
CultureInfo culture = new CultureInfo(CultureInfo.CurrentCulture.LCID);
try
{
DateTime.ParseExact( cc.Renderer.ControlText,"dd/MM/yyyy",culture,DateTimeStyles.AllowWhiteSpaces );
}
catch
{
cc.RejectChanges();
}

Please let me know if you have any further assistance.

Thanks for your interest in Syncfusion Products.

Hi Haneef,

thanks to your reply,

the code you gave work properly, but when i type an invalide date "35/35/2006" and hit the tab key nothing happens the first time, i need to hit another time the tab key so the changes will be rejected. so the changes are rejected the second time i hit the tab key and not the first time. do you have any idea to solve this issue ?

best regards and thanks in advance

Hi Fady,

Could you try this code.

GridCurrentCell cc = this.gridControl1.CurrentCell;
CultureInfo culture = new CultureInfo CultureInfo.CurrentCulture.LCID);
try
{
DateTime.ParseExact( cc.Renderer.ControlText,"dd/MM/yyyy",culture,DateTimeStyles.AllowWhiteSpaces );
}
catch
{
cc.Renderer.ControlValue = string.Empty;
}

Thanks for your patience.

Hi Haneef,

thanks to your reply,

the code you post work properly, but it set the cell to empty if the user enter a wrong date.
but i still need the old value of the cell.

for example :
the value in the cell before editing is "12/12/2005", now the user enter a wrong date "35/35/2005". when the user hit the tab key i need to get back to the old date witch is "12/12/2005" and not an empty string

best regards and thanks in advance

Hi Fady,

You need to use this code to get the old value of the cell in a grid.Here is a code snippet

GridCurrentCell cc = this.gridControl1.CurrentCell;
CultureInfo culture = new CultureInfo( CultureInfo.CurrentCulture.LCID);
try
{
DateTime.ParseExact( cc.Renderer.ControlText,"dd/MM/yyyy",culture,DateTimeStyles.AllowWhiteSpaces );
}
catch
{
cc.Renderer.ControlValue = this.gridControl1.Model[cc.RowIndex,cc.ColIndex].CellValue ;
}

Please let me know if this helps.
